Recitals


 


	A.	AgeX
    is a newly organized corporation that needs office and laboratory space and equipment, and the services of research, financial,
    management, and administrative personnel support;
	 	 
	B.	BioTime
    leases certain laboratory, office, and related work space at 1010 Atlantic Avenue, Alameda, California (the Premises)
    and has surplus capacity at the Premises; and
	 	 
	C.	BioTime
    has employees and contractors who provide research, financial, management, and administrative services and is willing to make
    a portion of their services available to AgeX;


 


1.
Office, Laboratory and Work Space.



 


(a)
BioTime agrees to permit AgeX to use the Premises concurrently with BioTime for the conduct of AgeX’s business operations,
but only to the extent that (a) the use is a business operation permitted to be conducted by BioTime under the lease of the Premises,
(b) AgeX uses the Premises in compliance with all applicable laws, ordinances, and regulations, (c) AgeX uses the Premises in
compliance with any and all rules and regulations of the landlord under BioTime’s lease of the Premises, (d) AgeX’s
use of the Premises does not interfere with BioTime’s use of the Premises.


 


(b)
BioTime and AgeX agree that the permission to use the Premises granted under this Agreement is in the nature of a license
only and is not a sublease or assignment of the lease under which BioTime occupies the Premises, and that AgeX shall not obtain
any rights, and is not assuming any obligations, under that lease.


 


(c)
The use of the Premises by AgeX shall be in a lawful, careful, safe, and proper manner, and AgeX shall not do or permit anything
to be done in or about the Premises that would increase the rate or affect any fire or other insurance covering the Premises.
AgeX shall not commit nor suffer any waste on the Premises.


 


(d)
BioTime does not represent or warrant that the Premises may be used for any particular use or purpose, and AgeX has made AgeX’s
own determination that the Premises may be lawfully used for AgeX’s purposes.


 


(e)
AgeX shall, at its sole cost and expense, comply with all laws, statutes, ordinances, and governmental rules, regulations,
or requirements now in force or that may hereafter be in force, and with the requirements of any board of fire insurance underwriters
or other similar bodies now or hereafter constituted, relating to, or affecting AgeX’s use of the Premises.


 




    	 



    	 



    

 


(f)
AgeX shall, at its sole cost and expense, promptly repair any damage to the Premises caused by any act or omission of AgeX
or its employees, agents, invitees, licenses, or contractors, including any acts or omissions of BioTime employees, contractors,
and agents arising in the course of performing services for or conducting the business of AgeX. Any and all repairs effected by
AgeX shall be performed in a professional workmanlike manner, by licensed contractors, in compliance with BioTime’s lease
of the Premises and all applicable statutes, codes, rules and regulations, and AgeX or AgeX’s contractors shall obtain all
permits and approvals of government agencies required by applicable laws in connection therewith.


 


(g)
BioTime deems any repairs required to be made by AgeX necessary, it may demand that AgeX make them, and if AgeX refuses or
neglects to commence such repairs and to complete them with reasonable dispatch, BioTime may make or cause such repairs to be
made. If BioTime makes or causes repairs to be made, BioTime shall not be responsible to AgeX for any loss or damage that may
accrue to AgeX’s business by reason of the repair work, and AgeX shall, on demand, immediately pay to BioTime the cost of
the repairs. AgeX waives the provisions of Sections 1941 and 1942 of the Civil Code of the State of California and all other statutes
or laws permitting repairs by a lessee at the expense of a lessor or to terminate a lease by reason of the condition of the Premises.
AgeX shall keep the Premises free from any liens arising out of any work performed, materials furnished, or obligations incurred
by AgeX.


 


(h)
AgeX shall not make or install any alterations, improvements, additions, or fixtures that affect the exterior or interior
of the Premises or any structural, mechanical, or electrical component of the Premises, or mark, paint, drill, or in any way deface
any floors, walls, ceilings, partitions, or any wood, stone, or iron work.


 


(i)
Under no circumstances shall AgeX bring onto the Premises any substances or materials that are characterized or defined as
“hazardous substances” or “hazardous materials” under any federal or state law or regulation pertaining
to the release of substances into the environment, except for cleaning materials, paints, and solvents that are used, stored,
and disposed of by AgeX in full compliance with applicable laws and BioTime’s lease of the Premises.


 


2.
Equipment and Supplies. BioTime agrees to permit AgeX to use BioTime’s office equipment, laboratory equipment, furniture,
laboratory supplies, and general office supplies to the extent that such use does not interfere with the use by the employees,
contractors, and agents of BioTime and other BioTime subsidiaries in the course of their business. BioTime shall have no obligation
to obtain or to provide AgeX with any additional equipment, furniture, or supplies. If AgeX requires and obtains equipment, furniture,
and supplies for its own use it may locate the same at the Premises subject to the conditions and limitations stated in Section
1 of this Agreement, and subject to the additional condition that BioTime shall have the right and sole discretion to (a) determine
where in the Premises AgeX may locate AgeX’s furniture, equipment, and supplies, and (b) preclude AgeX from bringing onto
or locating any furniture, supplies, or equipment in the Premises if BioTime determines that it would in any way interfere with
BioTime’s use of the Premises, violate any applicable laws, ordinances, and regulations, violate or conflict with any provisions
of BioTime’s lease of the Premises or any rules and regulations of the landlord under BioTime’s lease of the Premises,
conflict with any term or condition of any policy of casualty or liability insurance held by BioTime, or pose a hazard or other
risk to persons or property.

of conducting AgeX’s use. Utilities includes electricity, gas, heat, air conditioning, hot and cold domestic water,
telephone, scavenger service, garbage removal, sewerage, and other similar services used on, in, or in connection with the Premises.

(a)
BioTime shall provide basic accounting, billing, bookkeeping, payroll, treasury, collection of accounts receivable (excluding

and other professionals who may also provide professional services to BioTime and its other subsidiaries.


 


(b)
BioTime shall also provide AgeX with the services of its laboratory and research personnel (the Laboratory Services),
including BioTime employees and contractors, for the performance of research and development work for AgeX at the Premises. BioTime
employees and contractors who perform Laboratory Services for AgeX shall enter into agreements containing customary provisions
requiring the employees and contractors to (a) maintain the confidentiality and not to disclose AgeX trade secrets and other confidential
information, and (b) assign to AgeX all rights to any inventions and discoveries made by such employees and contractors in the
course of performing Laboratory Services for AgeX.


 


(c)
BioTime may, at the request of AgeX, provide AgeX the services of BioTime employees and contractors, including but not limited

Administrative Services, Laboratory Services, and Other Services (collectively, Services) shall be provided by BioTime
employees or contractors engaged by BioTime to provide such Services for the operation of BioTime’s own business. BioTime

(e)
AgeX shall be responsible for cooperating with BioTime’s officers, employees and contractors in such a manner as may
be reasonably required in order for the Services to be performed.


 


(f)
The Services shall be provided at the direction of AgeX; provided, that AgeX shall not request or direct any BioTime employee
or contractor to provide any Services or to take any other act that would violate any federal, state, or municipal law, statute,
ordinance, rule or regulation.


 


(g)
BioTime shall not be liable to AgeX for any loss or damages of any kind caused by, arising from, or in connection with (i)
the performance of Services performed by BioTime personnel, or the failure of any BioTime employee, contractor, or agent to perform
any Services, or (ii) any delay, error, or omission by any BioTime employee, contractor, or agent in the performance of Services
performed by BioTime personnel, except to the extent such loss or damage is the result of fraud, gross negligence or willful misconduct
by an BioTime employee, contractor, or agent.


 


5.
Use Fees.


 


(a)
AgeX shall pay BioTime the fees provided in this Section for the use of the Premises, equipment, supplies, professional services
(such as the services of attorneys, accountants, and consultants), and for the Services provided or agreed to be provided by BioTime
under this Agreement. For each billing period, BioTime shall equitably prorate and allocate its Employee Costs, Equipment Costs,
Insurance Costs, Lease Costs, Professional Costs, Software Costs, Supply Costs, and Utilities Costs, between BioTime and AgeX
based upon actual documented use and cost by or for AgeX or upon proportionate usage by BioTime and AgeX, as reasonably estimated
by BioTime. AgeX shall pay 105% of the allocated costs (the Use Fee). The allocated cost of BioTime employees and contractors
who provide Services shall be based upon records maintained of the number of hours of such personnel devoted to the performance
of Services.


 


(b)
The Use Fee shall be determined and invoiced to AgeX on a monthly basis for each calendar quarter of each calendar year (such
quarterly periods are sometimes referred to in this Agreement as “billing periods”). If this Agreement terminates
prior to the last day of a billing period, the Use Fee shall be determined for the number of days in the billing period elapsed
prior to the termination of this Agreement. Each invoice shall be payable in full by AgeX within 30 days after receipt. Any invoice
or portion thereof not paid in full when due shall bear interest at the rate of 15% per annum until paid, unless the failure to
make a payment is due to any inaction or delay in making a payment by BioTime employees from AgeX funds available for such purpose,
rather than from the unavailability of sufficient funds legally available for payment or from an act, omission, or delay by any
AgeX employee or agent.


 


(c)
In addition to the Use Fees, AgeX shall reimburse BioTime for any out of pocket costs incurred by BioTime for the purchase
of office supplies, laboratory supplies, and other goods and materials and services for the account or use of AgeX, provided that
invoices documenting such costs are delivered to AgeX with each invoice for the Use Fee. Notwithstanding this paragraph, BioTime
shall have no obligation to purchase or acquire any office supplies or other goods and materials or any services for AgeX, and
if any such supplies, goods, materials or services are obtained for AgeX, BioTime may arrange for the suppliers thereof to invoice
AgeX directly.

(d)
Employee Costs means the salaries, wages, health insurance benefits, FICA, payroll taxes, workers compensation insurance premiums,
and similar costs payable by BioTime to or on account of its employees and contractors who perform Services for AgeX under this
Agreement during an applicable billing period, but excluding stock option, stock purchase, and similar equity participation plans.
Equipment Costs means all costs and expenses incurred by BioTime in acquiring, leasing, installing, maintaining, insuring,
repairing, and disposing of any laboratory, production, and office equipment, fixtures, and furnishings used by AgeX or used by
BioTime in the performance of Services. Insurance Costs means all insurance premiums of any kind incurred or paid by BioTime
for casualty insurance policies that insure BioTime and its subsidiaries, including AgeX, from the loss of or damage to the Premises,
equipment, fixtures goods, supplies, and other personal property of BioTime (except to the extent such premiums are included in
Lease Costs) that may be used by AgeX or by BioTime in the performance of Services, and liability coverage policies that insure
BioTime and its subsidiaries, including AgeX, from liability of any kind to third parties (except to the extent such premiums
are included in Lease Costs). Lease Costs means all of BioTime’s costs and expenses of leasing the Premises, including
all base rent, taxes, common area or other expenses, insurance and other costs payable by BioTime to the lessor of the Premises
under the lease of the Premises, but excluding (a) any repairs not required to be effected or paid for by AgeX under any other
provision of this Agreement, and (b) any alterations or improvements effected by BioTime for the exclusive use of BioTime and
its subsidiaries other than AgeX. Professional Costs means all costs and expenses incurred by BioTime for the services
of independent accountants, attorneys, and other consultants who provide professional or consulting services for the benefit of
AgeX. Software Costs means all costs and expenses, including but not limited to license fees, incurred by BioTime to acquire
and use any computer software or program of any kind that is used by AgeX or by BioTime in the performance of Services. Supply
Costs means all costs and expenses incurred by BioTime for the purchase and disposal of goods and materials of any kind, to
the extent used in the performance of Services or used by AgeX employees or contractors. Utilities Costs means all costs
and expenses incurred by BioTime for the use or availability of Utilities during an applicable billing period.


 


(e)
Billing Dispute Resolution. If a disagreement arises between BioTime and AgeX with respect to any Use Fees charged by BioTime
under this Section 5 or by AgeX under Section 6, and AgeX and BioTime management are not able to reconcile or resolve the matter
within sixty (60) days of the first written notice disputing any charge or portion of the Use Fee, AgeX and BioTime shall engage
the services of a firm of certified public accountants to review the charges at issue and determine the amount due, which determination
shall be final and binding on AgeX and BioTime. AgeX and BioTime shall cooperate with the accounting firm to resolve the matter,
including making all relevant books and records available to the accounting firm for inspection and copying, and making employees
with knowledge relevant to the matter in dispute reasonably available to discuss the matter with representatives of the accounting
firm. The fees and expenses of the accounting firm shall be shared equally by AgeX and BioTime; provided, however, that if the
accounting firm determines that Use Fees or other charges were overstated by more than five percent (5%) and the amount of the
overstatement exceeds $100,000, the party that submitted invoices for the excessive fees or charges shall pay 100% of the fees
and charges of the accounting firm related to that matter. AgeX and BioTime agree that they will engage BDO USA, LLP (“BDO”)
for such services, but if BDO declines to perform the services AgeX and BioTime shall cooperate to select an alternative accounting
firm.

the consideration to BioTime, hereby assumes all risk of damage to property or injury to persons in, upon, or about the Premises,
from any cause other than BioTime’s willful malfeasance or sole gross negligence.

13.
Waivers, Delays, and Omissions. One or more waivers, consents, or approvals by any party of any covenant, condition, act,

act, or breach or as a consent or approval to the same or any other covenant or condition. This Agreement and any term of this
Agreement may be amended, discharged, or terminated only by a written instrument signed by the parties against whom enforcement
of such amendment, discharge, or termination is sought. No delay or omission to exercise any right, power, or remedy accruing

of BioTime’s rights and remedies under this Agreement. In the event an action is brought to enforce or interpret the provisions
of this Agreement, the prevailing party in such action shall be entitled to an award of its attorneys’ fees and costs incurred
